Stir together the onion soup mix and the water. Put all the ingredients in a bowl and mix together by hand. Once it is all combined, place the mixture in a 9x9 pan and press down to fill the pan. Squirt some more ketchup on top and rub it around to cover the meatloaf. Bake in a 400 degree oven for 45 minutes. Let rest 5 minutes before slicing.
